One Case, Both Tools: A Full Integration Walkthrough
Interleave the tools, don’t queue them

Lesson 3.1 · Page 1
Start here
Learning objective: Run a single case through the HSI Method and the HSI gut-restoration sequence simultaneously, demonstrating how the two tools interact rather than operate in sequence or isolation.
“Midway through an Assess, a client mentions an unrelated-sounding gut symptom almost in passing.”
Do you finish the five-domain scan first, or stop and pull in gut-specific thinking right then? What's the risk of each choice?
Lessons 1.5 and 2.5 each worked a full case — Aisha and Marcus — but each stayed within its own module's tool. Real cases are rarely that tidy: a client with gut symptoms usually also has a sleep problem, a stress problem, or a connection gap, and a client without obvious gut symptoms may still have undiagnosed dysbiosis contributing to something else entirely.
This lesson works one case where both tools are needed from the start, not applied one after the other as an afterthought.
Key Points
- Real cases don’t arrive pre-sorted into “Module 1” and “Module 2” material.
- A gut finding surfaced mid-Assess pulls Identify and Investigate in immediately.
- Deciding testing isn’t needed is a legitimate Investigate outcome, not a skipped step.
- Integrate links Regimen, the gut finding and Mind — and Connection & Purpose sustains the loop.
- Prioritise and Personalise draw on both tools at once.
- Measure tracks gut and whole-person markers side by side, reassessing at four weeks.
